6.6 Versions with integrated supply voltage
The potential-free supply voltage can energize a 2-wire transmitter or max. 4 control inputs. The output connections
can be selected with 3 S.I.L. switches:
Connections
Ü * Ö
Remarks
14(+) 12 (-) T open closed Only available, if INP1 is configured for current or thermocouple
4 (+) 1 (-) D closed open The voltage input of INP5 is not available
Factory setting:
Ü
= T,
*
= open,
Ö
= closed (T).
The unit must be withdrawn from the housing for changing
the switch positions.
The S.I.L. switches are located on the circuit board shown right.
* If A14/A12 is used for di1/di2, A12 must be connected with A1
6.7 Digital inputs and outputs (
r
connecting diagram)
The digital inputs and outputs must be energized from one or several 24 V DC sources. The current consumption is
5 mA per input. The max. load is 0,1 A per output. Examples:
Digital inputs (connector A) Digital inputs and outputs at one voltage
source (e.g. connector B) Digital inputs and outputs at two voltage
sources (e.g. connector B)
